Application filed December 1, 1919. Serial No. 341,706.

" To all whom it may concern:

Be it known that I, JOHN V. BUCKLE, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements in Drink-Mixers, of which the following is a spec1fication.

My invention relates to agitating machines, and has, for its object toprovide a means whereby one or more drinks may be mechanically mixed inseparate receptacles at the same time.

This object I accomplish with the device illustrated in the accompanyingdrawings in which similar letters and numerals of reference indicatelike parts throughout the several figures and as described in thespecification forming a part of this application and pointed out in theappended claims.

In the drawings in which I haveshown a substantial embodiment of myinvention, Figure l is a front elevation of the device with a glassreceptacle therein shown in dotted lines. Fig. 2 is an end elevation ofthe same. Fig. 3 is a vertical section of the supporting standard online 3-3 of Fig. 1. Fig. 4 is a plan view of the receptacle holdingmeans. Fig. 5 is a plan and edge view of one of the agitating arms. Fig.6 is a plan view of the horizontal shaft with a section through itsbearing to show the means for preventing end thrust. Fig. 7 is a sideelevation of my drink mixer, showing two of the units in full lines anda portion of another unit in dotted lines, parts of the base plate,motor standard and motor cut awa M; invention is principally for use indrink dispensing places, and especially for uickly and thoroughly mixingthe ingredients for such drinks as malted milk, and the like, andwherein the agitating elements are moved by a small electric motor whichis only energized when one or more of the agitators are in use, and fromwhich motor, all of the other parts of the device are insulated. Onespecial feature is to provide an economical device whereby one or moredrinks may be separately mixed at one time. Another feature is toprovide a mixer which will mechanically and thoroughly mix the liquidwithout spilling any.

The present invention consists of a base plate A, preferably made ofonyx or marble and on which the other parts of my devlce are mounted;The electric motor B 1s fastened on the upper end of'a hollow standardC. A sleeve 1, made of insulating material, has one end thereof securedon the motor shaft D. Another hollow standard 2 is vertically mounted onand firmly secured to said base plate A, and within wh1ch' standard ,islongitudinally operated the contact plunger 3 and the agitator support.Electric wires a and b are carried in the said standard C and with leadson the lower side of said base plate A to an openmg or hole in said baseplate below the lower end of said standard 2, where said wires arefastened in spaced apart relation to each other and act as contact postsagainst which the contact member 5 on the end of said plunger 3 is heldto form an electric circult in which is included a source of electr oenergy, not shown, with which the said wires a and b are connected. Thesaid agitator support consists of a sleeve l slidably and rotatablyoperated within said standard 2, and normally held in an extendedposition as shown in dotted lines in Fig. 3 by the spiralfspring 6carried around, said plunger 3. One end of said spring 6 is fastened toa thimble7 that in turn is securredin the lower end of said standard 2,while the other end of said spring bears against a collar sleeve 8 whichis in turn fastened in the upper end of said sleeve 4. A. yieldinglyheld dog 9 is pivoted in a bearing bracket 10 which is secured on theupper portion of said standard 2, and said dog is formed to engage thebase of a thumb piece 11, that is secured on the upper end of saidplunger 3. An insulating plug 12 is fastened on the lower end of saidplunger 3 and said contact 5 is fastened in or to said plug, therebyinsulating said contact from all ofthe parts of my device except when itis brou t in contact with said wires a and b. Y-shaped bearing member 13is secured on the upper end of said sleeve 4 by the said thumb piece 11being screwed on the upper portion of said plunger 3 and a shoulder 14on said plunger bearing against the lower side of said collar sleeve 8,which in turn bears against the lower side of said Y-shaped bearingmember 13. The agitator shaft 15 is carried and journaled in saidY-shaped bearing member and is thereby held vertically and outwardly ina mild way while the other is positioned'above the lower end of saidshaft and with its blades inclined to move the liquid downwardly as wellas outwardly. A

receptacle holder 19 is fastened at one end to said standard 2 and ismade of spring material to yieldingly retain a receptacle'20 when placedtherein and resting on said base plate A. A horizontal shaft 21 ismounted for rotation in the said bearing bracket 10 and with one endsecured in the insulating sleeve 1. A friction disk 22 is secured on andmade to rotate with said shaft 21 by the pin 23 which is passed throughthe hub of said friction disk then through said insulating sleeve 1 andthrough said shaft 21. I designate all of my device from the line w-wtoward the right in Fig. 1, an agitating unit, and I provide as manyagitating units as may be,

desired in order that more than one receptacle full of liquid may bemixed at the same time, by extending the base plate A, or adding anotherplate and duplicating all parts of my device from the lineXv-w. To dothis a hole 24 is provided in the free end of each of said horizontalshafts 21, and the horizontal shaft 21 of the added unit is secured onthe end of the first or any added shaft 21 by a duplication of pin 23,and connecting the wires a and b of each added unit with the wires ofthe preceding unit at the bolts 25 shown in Fig. 3. The electricconnection may be made by the operator of any unit by throwing his unitinto mixing position. The different elements of the second unit of mydevice are indicated by the same respective reference numerals used inthe first unit with the addition of a prime mark to indicate that it isan element of the second unit, and as far as shown in Fig. 7 thereference numerals are respectively given the double prime mark thus toindicate that they belong to the third unit.

The operation of my device is as follows: With a source of electricenergy provided to drive the motor B when it is brought into thecircuit, and with the agitating means turned in the position shown indotted lines 1n Fig. 3, the contact member 5, "insulating plug 12 andlower end of the plunger 3 I will be about on a level with the upperedge of the receptacle 20; while the agitating shaft and lower agitatingarm' 18 will be above the plane of the upper edge of the mixingreceptacle M 20 thus allowing free swinging of the agitating members.When be completed and the motor with the shaft 21 will'be rotated. Thedog 9 will engage the flange portion of the thumb piece 11 and hold theagitating elements in the position shown in Fig. 1. -With the frictionelements 16 and 22 engaged, rotation will be imparted to said arms '18and the liquids thoroughly mixed without any tendmay to throw thecontents of the receptacle over its edge. By pressing down on the thumbportion of the dog 9 to release it from its engagement with said thumbpiece 11, the spring 6,/will move the agitating elements verticallyupward and the electric circuit will be broken. The agitating means maythen be swung from over the receptacle to the position shown in Fig. 3.If another operator is using another unit farther away from the motor hemay complete the electric circuit by making a contact with his contactplug 5 and wires a and b, and the removal of any-contact 5 from betweenthe wires a and b will affect only the unit so operated. By using ballbearings 26 with a slidable race plate 27, and adjustable collar 28 I amable to hold the friction elements 22 and 16 without end thrust on themotor shaft D.

I thus provide new and novel agitating means to prevent spilling of thecontents of the receptacle; new and novel means for rotating the aitator; as well as new and novel means or economically and mechanicallyagitating one or more liquid mix-- tures at the same time.

Having thus described my invention and its operation I desire tosecureby Letters Patent and claim 1.
